I really hope Spyderco is keeping the liners for the upcoming FRN/LW PM2.

I wouldn't buy this knife, but count me in as part of the crowd that always prefers liners with FRN.

I generally have the impression that Spyderco moves a bit in the linerless direction, both with G10 and FRN. Even the Stretch XL will be linerless though no Salt and though the "regular" Stretch does have liners.

For me understandable:
I figure Spyderco invested a lot in that technology or in getting that good in making linerless FRN knives. Now that they are where they are it would be weird not to make use of that and by that folders easier to produce and more cost effective.
This is also true for almost linerless comp. lock models. I can recall that it was a "small sensation" when the Para 3 LW came out as the first such model.

I never felt that liners are necessary technically speaking, and I don't baby my knives at all.

I'll add as I have to many similar threads, the only time I've seen an FRN handle broken on this forum was when someone had their Salt 1 stuck blade first into the ground and ran it over with a Bobcat track. It's incredibly tough stuff, even without liners and needs nonsensical use to risk failure.
